Check keyword density online to avoid over-optimization. Analyze any text for keyword frequency, word counts, and balanced SEO writing with a free tool.

Picture a page repeating "affordable plumber" forty times in five hundred words. A decade ago it might have ranked; today it reads as spam to visitors and to Google alike. Yet the opposite mistake is just as common: a thoughtful article that never uses the terms people search for. A Keyword Density Analyzer sits between those two extremes and shows you exactly where your content lands.

h2>What the analyzer actually measures

Paste in your draft and the tool breaks it down in seconds. You get a total word count, then a ranked list of the words and phrases that appear most often, each with its count and its share of the whole text. Two and three-word phrases are tracked separately, which matters because search is usually about phrases like "keyword density checker", not single words. Treat it as a diagnostic view, not a grade: the numbers describe your draft, and you decide what to change.

Checking a draft in five steps

1. Open the analyzer and paste your article text into the input box.
2. Run the analysis to generate the frequency table.
3. Scan the top ten phrases and compare them with the terms you meant to target.
4. Look for any phrase climbing past two percent and rewrite those sentences more naturally.
5. Re-run the check after editing to confirm the balance improved.

That final re-check matters: editing by feel often swings a page from stuffed to starved.

What counts as a good density?

Here is the honest answer: there is no magic number. The old "keep it between one and two percent" rule was folklore even when it was popular, and Google's guidance talks about writing for people, not hitting a ratio. Use the analyzer as a sanity check: if your main phrase sits near one percent with synonyms filling out the rest, you are fine. If one phrase dominates at four or five percent, rewrite for variety.

Mistakes the tool helps you catch

• Repeating the exact phrase: search engines understand variants, so "density checker", "density tool", and "check density" can share the load.
• Ignoring the words around your keyword: a page about a tool should also mention words like "online", "free", "analyze", and "results" naturally.
• Skipping long-tail phrases: three and four-word phrases often convert better and face less competition.
• Front-loading the introduction: cramming every keyword into the first paragraph reads badly and skews the whole analysis.

Frequently asked questions

Does keyword density still matter for SEO?

It matters as a hygiene check, not as a ranking trick. A balanced page tends to cover its topic well, which is what actually ranks. The analyzer keeps you from drifting into spam territory.

What density should I aim for?

There is no official target. Most natural pages land their main phrase between half a percent and two percent; treat anything much higher as a prompt to rewrite.

Can it analyze a live page or only pasted text?

The analyzer works on text you paste in. For a published page, copy the body text and paste it into the tool.

Is over-optimization a real risk?

Yes. Pages written for crawlers rather than people earn fewer links and higher bounce rates. Natural writing is the safer strategy every time.

Final thoughts

A keyword density analyzer will not choose your keywords or write your content, but it gives you something most writers lack: an objective mirror. Pair it with a broader SEO Analyzer check, and once the page is live, validate your structured data with the JSON-LD Validator. Balanced, human writing plus clean technical SEO is a combination that holds up.
